       catal - catalog file format


       Predefined libraries
              The  environment  variable MBK_CATA_LIB(1) defines several paths
              corresponding to the Alliance predefined cell  libraries.   Each
              library is in one unix directory.

              sxlib               standard cell library

              dp_sxlib            data-path compiler library

              rflib               registers library

              ramlib              ram library

              romlib              rom library

              padlib              pads lib

              For  each  library,  a  special  file  named CATAL describes the
                                  contents.  This file must  be  in  the  same
                                  directory  as  the  library  cells.  For the
                                  Alliance tools, the cells described  in  the
                                  predefined libraries are read only.

       The working library
              The  environment  variable  MBK_WORK_LIB(1)  defines the current
              working  directory.   Its  default  value  is  .  (dot).    This
              directory will contain the user cells, seen as read write by the
              Alliance tools.  It is not necessary to describe  all  the  user
              cells  in  a  catalog  file.   But the user can locally define a
              catalog file for the working library.  The  local  catalog  file
              name is set by the environment variable MBK_CATAL_NAME(1), CATAL
              by default.  Alliance will concatenate all catalog files of  the
              predefined  libraries  and  the  optional  catalog  file  of the
              working library to access the attributs of each cell.

       Cells attributs
              A cell may be characterized by four attributs:

              C                   this attribut means that the cell is a  leaf
                                  cell  in the context of a recursive flatten,
                                  for either the layout or netlist view.   The
                                  cell will not be flattened.

              G                   this  attribut  means  that  the cell has an
                                  existing    equivalent    GDS     or     CIF
                                  representation.   It is used by the symbolic
                                  to real translation tool,  s2r(1),  to  make
                                  direct replacements.

              F                   this attribut means that the cell is used as
                                  a feed through.

              D                   this attribut  is  used  only  in  the  user
                                  defined catalog.  As the user is not allowed
                                  to delete a cell in a predefined library, it
                                  is  possible to virtually remove a cell of a
                                  predefined library with the  D  attribut  in
                                  the user defined catalog.
